• When TGR is an output compare register
• When TGR is an input capture register
Example of Buffer Operation Setting Procedure: Figure 11.15 shows an example of the buffer
operation setting procedure.
When a compare match occurs, the value in the buffer register for the corresponding channel is
transferred to the timer general register.
This operation is illustrated in figure 11.13.
When input capture occurs, the value in TCNT is transferred to TGR and the value previously
held in the timer general register is transferred to the buffer register.
This operation is illustrated in figure 11.14.
